Effects of temperature, pH and counterions on the stability of peptide amphiphile nanofiber structures
(Royal Society of Chemistry, 2016)Peptide amphiphiles are a class of self-assembling molecules that are widely used to form bioactive nanostructures for various applications in bionanomedicine. However, peptide molecules can exhibit distinct behaviors under ... -
Fabrication of supramolecular n/p-nanowires via coassembly of oppositely charged peptide-chromophore systems in aqueous media
(American Chemical Society, 2017-07)Fabrication of supramolecular electroactive materials at the nanoscale with well-defined size, shape, composition, and organization in aqueous medium is a current challenge. Herein we report construction of supramolecular ... -
Hierarchical self-assembly of histidine-functionalized peptide amphiphiles into supramolecular chiral nanostructures
(American Chemical Society, 2017)Controlling the hierarchical organization of self-assembling peptide amphiphiles into supramolecular nanostructures opens up the possibility of developing biocompatible functional supramolecular materials for various ... -
Magnetization of graphane by dehydrogenation
(AIP Publishing, 2009)Using first principles calculations, we show that each hydrogen vacancy created at graphane surface results in a local unpaired spin. For domains of hydrogen vacancies the situation is, however, complex and depends on the ... -
Polarization‐enhanced hydrogen bonding in 1,8‐dihydroxynaphthalene: conformational analysis, binding studies and hydrogen bonding catalysis
(Wiley, 2020-11-16)In this article, the presence and effects of polarization‐enhanced hydrogen bonding in 1,8‐dihydroxynaphthalene (1,8‐DHN) were investigated in detail through a series of experimental and computational studies. First, the ... -
Polymer/clay nanocomposites through multiple hydrogen-bonding interactions
(John Wiley and Sons Inc., 2015)An 2-ureido-4[1H]pyrimidinone (UPy) motif with self-association capability (through quadruple hydrogen bonds) was successfully anchored onto montmorillonite clay layers. Polymer/clay nanocomposites were prepared by specific ... -
Single-site mutation and secondary structure stability: an isodesmic reaction approach. The case of unnatural amino acid mutagenesis Ala→Lac
(American Chemical Society, 2004)A method is described to evaluate backbone interactions in proteins via computational unnatural amino acid mutagenesis. Several N-acetyl polyalanyl amides (AcA nNH 2) were optimized in the representative helical (3 10-, 4 ... -
Structural and loss characterization of SiON layers for optical waveguide applications
(IEEE, 2000)Silicon oxynitride films for optical waveguide applications were grown at 350°C in a PECVD reactor. ATR-FTIR spectroscopy was used to identify the bond structure and absorption characteristics in the mid-infrared region. ...
